Community Dwelling Older People

Accelerometer-derived estimates of physical activity (PA) and sedentary time have been an important methodological focus. However, little is known about the daily activities among older people during their normal lives. Furthermore, some older individuals would like to be more active, yet experience an unmet PA need, which is defined as the desire to engage in more PA but without the opportunity to act on the desire. This study examined the intensity of daily PA and sedentary behavior measured with accelerometers among older people, and whether PA differs between weekdays and weekends and those with and without the experience of unmet PA need, measured with self-reports. A total of 174 community-dwelling older people (64% female) aged 75 to 90 years used an accelerometer for 7 consecutive days during waking hours, and the results were classified for sedentary behavior (thresholds of 0.0167 g), light activity (0.091 g), and moderate-to-vigorous activity (MVPA, 0.414 g) based on mean amplitude deviation (g). We found that during weekdays, older people engaged slightly more in light activity and had less sedentary time than during weekends. In total, 7.6% of the participants perceived an unmet PA need. Accordingly, those with unmet PA needs spent less time in MVPA, especially during weekdays, and they might benefit from PA-enabling interventions.

Objectives:To characterize patterns of sedentary behavior and physical activity in older adults recovering from hip fracture and to determine characteristics associated with activity.Methods:Community-dwelling, Canadian adults (65 years+) who sustained hip fracture wore an accelerometer at the waist for seven days and provided information on quality of life, falls self-efficacy, cognitive functioning, and mobility.Results:There were 53 older adults (mean age [SD] 79.5 [7.8] years) enrolled in the study; 49 had valid data and demonstrated high levels of sedentary time (median [p10, p90] 591.3 [482.2, 707.2] minutes/day), low levels of light activity (186.6 [72.6, 293.7]), and MVPA (2 [0.1, 27.6]), as well as few daily steps (2467.7 [617.1, 6820.4]). Regression analyses showed that age, gender, gait speed, and time since fracture were associated with outcomes.Conclusions:Older adults have long periods of sedentary time with minimal activity. Results are a call to action to encourage people to sit less and move more.

The Relationship

Objective: This study aims to assess the relationship that frailty has with nutritional status and functional risk factors in community-dwelling older adults. Methods: Cross-sectional study in community-dwelling older people, independent for walking and without impaired cognition. Frailty was assessed by Fried criteria. Nutritional status was analyzed by the Mini Nutritional Assessment Short Form (MNA-SF), biochemical markers (albumin, total proteins, cholesterol, lymphocytes, and hemoglobin); and anthropometric parameters (body mass index [BMI], body fat percentage, handgrip, and perimeters). A comprehensive geriatric assessment analyzed other risk factors: functionality, cognition, falls, comorbidity, polypharmacy, physical activity, and quality of life (QoL). Results: We included 564 elderly people with a mean age of 76.05 (standard deviation 3.97) years; 63.1% (n = 356) were women, and 83.9% (n = 473) were prefrail, and frail. The sample presented high functionality and a nutritional status with a predominance of overweight and obesity. Factors associated with frailty (R2 = 0.43) were age over 75 years (odds ratio [OR] 3.31, 95% confidence interval [CI] 1.76, 6.21; p < 0.001), female gender (OR 2.37, 95% CI 1.24, 4.52; p = 0.009), anemia (OR 2.45, 95% CI 1.19, 5.02; p = 0.015), falls (OR 1.94, 95% CI 1.12, 3.25; p = 0.016) and the fear of falling (OR 4.01: 95% CI 1.76, 9.16; p = 0.001). Performing more than 3 weekly hours of physical activity was found to be a protective factor (OR 0.23, 95% CI 0.15, 0.35; p < 0.001). Conclusions: The relationship between frailty and malnutrition in functionally independent community-dwelling older people is unclear. More studies are needed to know what nutritional markers are related to frailty, cognition, and functionality in order to discriminate the risk factors for community-dwelling older people at risk of malnutrition and dependency.

AbstractDespite the well-documented health benefits of physical activity in older adults, participation levels remain low. With rapid global population ageing, intensive efforts are needed to encourage higher levels of participation to ameliorate the negative effects of physical inactivity for older individuals and society as a whole. The aim of this qualitative study was to inform future physical activity promotion interventions by examining factors contributing to low activity levels among older people undertaking less than half the recommended level of moderate-to-vigorous physical activity (MVPA). Semi-structured interviews were conducted with 102 (65% female) community-dwelling Western Australians aged 60+ years (mean = 71.52, standard deviation = 6.26) who engaged in ⩽75 minutes of MVPA per week as measured by accelerometers. Several modifiable and unmodifiable barriers were identified, of which poor health featured most prominently. Lifetime physical inactivity, caring duties, low motivation, misperceptions of physical activity and ageing, and a lack of affordable and attractive options were the other barriers identified. The results suggest that strategies are needed to raise awareness of current physical activity guidelines, normalise engagement in MVPA throughout the lifespan, develop initiatives to motivate participation, improve the availability of affordable physical activity programmes that are attractive to this population segment, and facilitate participation among those with intensive caring responsibilities.

Community Dwelling Older Adults

Abstract Introduction Physical activity (PA) is important for older people to maintain functional independence and healthy ageing. PA interventions for community-dwelling older adults are often delivered by healthcare professionals, fitness instructors or trained members of a research team. Innovative approaches are needed to ensure that these interventions are practical and sustainable. This systematic review explores the effectiveness of volunteer-led PA interventions in improving health outcomes for community-dwelling older people. Methods Following PRISMA recommendations, five databases (MEDLINE, Embase, CINAHL, PEDro, Cochrane library) were systematically searched until May 2019, for studies using trained volunteers to deliver PA interventions for community-dwelling older people aged ≥ 65 years, reporting on participant outcomes. Meta-analysis was not conducted due to included study heterogeneity. Results Twelve papers (eight studies including three randomised controlled trials (RCTs)) were included in the review; five papers reported different outcomes from the same RCT. Intervention settings included community exercise groups (n=4), home (n=2) and care homes (n=2). All eight studies included strength and balance exercises and frequency of PA ranged from once daily to weekly sessions. The three RCTs showed improvement in grip strength, nutritional and frailty status, and reduction in fear of falling, among 39 older adults (mean age 83 years) who received a physical training and nutritional intervention; improvement in grip strength and activity of daily living scores among 56 nursing home older adults (mean age 78 years) who received resistance exercise training; and a significantly higher proportion of older adults (n = 193, 9% improvement vs 0.5% in the control group) achieved the recommended target of 150 minutes of moderate vigorous PA per week using the Falls Management Exercise intervention. Two studies compared volunteer and health professional-delivered PA interventions and reported that both interventions were equally effective in reducing fear of falls and improving quality of life. Two quasi-experimental studies reported improvement in functional outcomes including functional reach, timed up and go test, and chair stand. A large prospective cohort study (n = 1620) reported a reduction in disability among older adults who received volunteer-led exercise compared to control, with a hazard ratio of 0.73 (95% CI 0.62-0.86) for development of disability. Conclusions Trained volunteers can lead PA interventions among community-dwelling older adults with some evidence of improved health outcomes including nutritional, functional and frailty status.

Abstract Background This study aimed to develop cut-points for the 30-item and 10-item Iconographical Falls Efficacy Scale (IconFES) in community-dwelling older people and evaluate the psychometric properties, including construct and predictive validity with respect to falls and reduced physical activity over 1 year. Methods Eight hundred and one participants completed the IconFES and underwent physical, psychological and cognitive measures at baseline. Physical activity was recorded at baseline and 12 months using an activity monitor, and 1-year fall incidence was collected using monthly falls calendars. Results Using receiver-operating characteristic curves and the Youden’s index for history of falls, physiological fall risk and depressive symptoms, cut-points were defined to differentiate between low and high concern about falling (30-item: &lt;53; 10-item: &lt;19). For the 30-item IconFES, we additionally defined cut-points for low (≤40), moderate (41–58) and high (≥59) concern about falling. Groups based on these cut-points differed significantly: low coordinated stability, executive function and amount of daily walking, and high level of disability (30-item version) and female gender (low/high 30-item version). Although there were some inconsistencies across IconFES classifications, high concern about falling predicted having had multiple falls or multiple/injurious falls, low amount of daily walking and low movement intensity at 12 months. Conclusions The developed IconFES cut-points were sensitive to variables associated with concern about falling and predicted fall incidence and physical activity restriction after 12 months. Applying these cut-points appears useful to identify older people with high concern about falling, who are at higher risk of falls and activity curtailment.

Objective: to investigate the factors associated with sarcopenia and sarcopenic obesity (SO) in community-dwelling older people. Methods: This was a cross-sectional community-based study. Sarcopenia was diagnosed according to the cutoff points of hand grip strength (HGS), and SO was identified through a low HGS concomitant with a high body fat percentage, according to sex, determined using electrical bioimpedance. Calorie and protein intake was estimated using a 24-hour recall. Socio-demographic data were obtained by means of an interview and the level of physical activity was assessed using a specific instrument. Results: Prevalence of 43% and 19.6% were observed for sarcopenia and SO, respectively. Older people aged ≥ 70 years have a significantly higher risk for sarcopenia in 183% (PR = 2.83; 95% CI = [1.62 to 4.96]; p value < 0.001) compared to those aged 60 to 69 years. The prevalence of sarcopenia was higher in males, among those who contribute to family support, present comorbidities and are less physically active. The prevalence of SO and sarcopenia was high, but this study did not allow us to observe statistically significant associations. Calorie and protein intakes were predominantly inadequate throughout the sample, however, there was no association with sarcopenia and SO. Conclusion: Advance years of life was shown to be a factor associated with sarcopenia, and with SO. Contributing to family support and insufficient physical activity were determining conditions for the occurrence of sarcopenia.

Sedentary Bouts

Long periods of sedentary behavior (SB) is detrimental for health. This study investigated SB in older African American women (OAAW) and further compared it between participants of different physical activity status. Twenty OAAW had their sedentary time measured by accelerometers for seven consecutive days. Actigraph 6 processed accelerometer data and SPSS was used for statistical analysis with significance set at p < .05. Our sample spent approximately 9 hours in SB with an average of 27 breaks of sedentary time per day. The inactive group had higher amounts of time ( p < .01) on the average length of sedentary bout and the average number of sedentary bouts longer than 30 minutes compared with the active group. OAAW spend large amounts of their awaking hours in sedentary activities. The findings suggest that the inactive women may be at increased health risk based on the low levels of physical activity and the prolonged sedentary bouts.
